She has an Academy Award, an adorable daughter and a sexy fiancé, and now Halle Berry is adding a new blessing to her already charmed life: a new baby!

“I feel fantastic!” gushes The Call actress about her impending arrival. While she wouldn’t confirm reports that she’s expecting a boy with fiancé Oliver Martinez, she did admit her shock at second motherhood: “This has been the biggest surprise of my life… Thought I was past the point where this could be a reality for me. So it’s been a big surprise, and the most wonderful.”

Star‘s insider reveals that Halle wasn’t using birth control, but never expected to get pregnant, given how she struggled to conceive her five year old daughter, Nahla, with then-boyfriend Gabriel Aubry.

Though blessed, Halle and Oliver worry that her advanced age may complicate the pregnancy. “Halle is over-the-moon happy but very stressed,” explains the friend. “She is taking extra care of her body in order to have a successful body and a healthy pregnancy.”

Luckily for her, Olivier, 47, is already a hands-on dad. “He’s been amazing with Halle!” says the pal. “He caters to her and makes sure she is happy and comfortable.” Congratulations!
